What occurs as a result of fibrous adhesions in the joint capsule?

Fibrous adhesions in the joint capsule are pathological changes that occur in response to injury, inflammation, or prolonged immobility. These adhesions create areas of scar tissue that can limit the flexibility and movement of the joint. When fibrous tissues develop within the joint capsule, they restrict the normal sliding and gliding mechanisms of the joint surfaces during movement. As a result, the joint is unable to achieve its full range of motion.

In contrast, options that suggest increased range of motion, enhanced muscle strength, or improved joint lubrication do not align with the physiological impact of fibrous adhesions. Increased range of motion would entail greater flexibility and movement capability, which is exactly what fibrous adhesions inhibit. Similarly, enhanced muscle strength and improved joint lubrication are not directly associated with adhesions; instead, these factors often require an optimal state of joint health without restrictive fibrous tissue. Therefore, the most accurate outcome of fibrous adhesions in the joint capsule is a decreased range of motion.
